[WebAssembly] Added default stack-only instruction mode for MC. Summary: Made it convert from register to stack based instructions, and removed the registers. Fixes to related code that was expecting register based instructions. Added the correct testing flag to all tests, depending on what the format they were expecting so far. Translated one test to stack format as example: reg-stackify-stack.ll tested: llvm-lit -v `find test -name WebAssembly` unittests/MC/* Reviewers: dschuff, sunfish Subscribers: sbc100, jgravelle-google, eraman, aheejin, llvm-commits, jfb Differential Revision: https://reviews.llvm.org/D51241 llvm-svn: 340750

[WebAssembly] replaced .param/.result by .functype Summary: This makes it easier/cleaner to generate a single signature from this directive. Also: - Adds the symbol name, such that we don't depend on the location of this directive anymore. - Actually constructs the signature in the assembler, and make the assembler own it. - Refactor the use of MVT vs ValType in the streamer and assembler to require less conversions overall. - Changed 700 or so tests to use it.
